GREAM-SEPARATOR.

Specification of Letters Patent.

Application filed July 23, 1909. Serial No. 509,248,

To all whom it may concern:

Be it known that I, GUsrAr THEODOR SonnRs'rRoM, of Renfrew, in the Province of Ontario, Canada, have invented certain new and the'objects of my invention are to provide an improved distributing member which will permit the tree inward passage 'of the cream without interfering with the outgoing milk, and which will, at the same time, e 'ect a partial separation of the full plates, and it consists'essentiallyof a distributing member formed with a plurality of spirally inclined plates which extend to the inner edge of the liner plates, the said distributio member being supplied, at the center, wit milk, all as hereinaftermore fully set forth and described in detail in the accompanying specifications and drawings.

In the drawings, Figure l is a sectional perspective View of the bowl. Fig. '2 is a horizontal section through the same,

- In the drawings", like figures of reference indicate corresponding parts in each figure. Referring to the drawings, A represents the bowl of any suitable shape, and B the supporting shaft therefor, connected thereto in'the usual manner and rotated by suitable means not illustrated.

C represents the liner plates on the interior of the bowl of'usual conoidal form, and spaced a short distance apart.

D represents the central distributing member which, in the. embodiment illustrated, is formed integral with the base of the bowl. This distributing member is formed with a tubular central portion 10 into which the full milk is introduced by suitable means, the said central portion being-provided with apertures 11 at substantially'the center of the liner plates, through which the milk may pass into the bowl.

' In accordance with the present, invention, the distributing member 1s formed on the exterior with a plurality of spirally curved d1stributin'g wings 12, which extend out wardly a short distance to the inner edge of readily moved from the tubular central por tion' of the distributing member, whereby an annular space 13 will be provided bet-ween.

Patented Mar. 1, 1910.

the liner plates (3, the said inner edge being In operation, the bowl is driven in the direction of the arrows in Fig. 2, and the full milk is fed into the central distributing member. It passes through the apertures 11. and. out along the inner or concave side of the wings 12 into the liner plates. At the same time, thelseparated cream will be moving inwardly and upwardly along the outer or convex side of the wings 12. and it will finally pass out a suitable outlet 14-. The separated milk will pass to the exterior of the liner plates and up along' the annular space provided between the outer edge of the liner plates and the inner periphery of the bowl, finally passing out the outlet 15.

It will be observed that the space between the distributing wings is .much greater than the width of the wings themselves, and consequently, access may be readily had to the interior of the distributing-meniber and the milk willhave a full clear space in passing outwardly, much better than it would have if the wings were perforated in form. I

In describing the central distributing wings, in the following claim, the terms upper and lower portions are used.

The term u er ortion is intended to refer to the upper tubular portion extending through the bowl of the separator, while the term lower portion is intended to refer to that portion which extends upwardly from thebottom of the bowl and surrounds the spindle B.

What I claim as my invention is A cream separator having a bowl, a plurality of parallel conoidal liner plates spaced a short distance apart, and a central division member having atubular portion extending through the top of the bowl, said tubular portion being cut away circumferentially a portion of its length, a plurality of solid spirally shaped distributing wings having their inner e ges integrally connected to said eee eee tubular pei'tien and s aced between said cut In Witness Whereef I have hereunto set my away portions and t e outer edges thereof hand 1n the presence of two witnesses.

extending to the inner edges of the liner plates, the space between said Wings being USAF THEODOR SODERSTROM' 5 of much greater Width than the wings them "Witnesses:
